Protocol describes how to generate a plasmid construct (pBAIT) that expresses a target protein fused to the bacterial LexA protein. PBAIT is cotransformed into yeast with a lexAop-lacZ reporter plasmid carrying the bacterial lacZ gene under the control of the lexA operator. The recipient yeast strain contains a chromosomally integrated leu2 reporter gene, also under the control of the lexA operator. - [Read Two-hybrid Systems Stage 1: Characterization of a Bait-LexA Fusion Protein Protocol]
